allowing for the execution of arbitrary code.

<p>
The Xiph.org Free Lossless Audio Codec (FLAC) library is the reference
implementation of the FLAC audio file format. It contains encoders and
decoders in library and executable form.

<description>
<p>
Sean de Regge reported multiple integer overflows when processing FLAC
media files that could lead to improper memory allocations resulting in
heap-based buffer overflows.
</p>
</description>
<impact type="normal">
<p>
A remote attacker could entice a user to open a specially crafted FLAC
file or network stream with an application using FLAC. This might lead
to the execution of arbitrary code with privileges of the user playing
the file.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All FLAC users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-libs/flac-1.2.1-r1&quot;</code>
<p>
You should also run revdep-rebuild to rebuild any packages that depend
on older versions of FLAC:
</p>
<code>
# revdep-rebuild --library=libFLAC.*</code>
